Docking and molecular biology studies of -anisidine-appended 1-hydroxy-2-acetonapthanone Schiff base lanthanum(iii) complexes.

A new series of lanthanum(iii) complexes was synthesized using a -anisidine-appended 1-hydroxy-2-acetonapthanone (3) Schiff base and characterized spectroscopic methods. The ligand was synthesized sonication and the crystalline product was characterized using X-ray crystallography. The genotoxicity of the compound was assessed primarily by the bacterial reverse mutation (Ames) test and the mammalian chromosome aberration test; in both cases, the samarium complex 5 was found to be non-mutagenic.

A study to assess expression of human papillomavirus types 16 and 18 in oral squamous cell carcinoma using polymerase chain reaction.

Objective: The diverse subset of oral squamous cell carcinoma (OSCC) with different clinical appearance and outcome, independent of traditional risk factors has led to increasing attention in human papillomavirus (HPV) infection.

Materials And Methods: The investigation followed a case-control design. Information pertaining to the subjects was retrieved from hospital records.

Discrimination of periodontal diseases using diffuse reflectance spectral intensity ratios.

This clinical study was to demonstrate the applicability of diffuse reflectance (DR) intensity ratio R620/R575 in the quantification and discrimination of periodontitis and gingivitis from healthy gingiva. DR spectral measurements were carried out with white-light illumination from 70 healthy sites in 30 healthy volunteers, and 63 gingivitis- and 58 periodontitis-infected sites in 60 patients. Clinical parameters such as probing pocket depth, clinical attachment level, and gingival index were recorded in patient population.

Nidus localization in osteod osteoma by SPECT skeletal scintigraphy: Aid to diagnosis and surgical approach.

Osteod osteoma, although not a common clinical occurrence, does pose problems both in diagnosis and surgical management. Initial plain radiographic diagnosis is sometimes fraught with the limitation of not being able to differentiate from chronic osteomyelitis and stress fracture. CT-aided localization of the nidus is also often inconclusive.
